Answered as they actually are today, not as they will be once even has run enough briefs to know more. Where the honest answer is that something is not solved yet, that is what it says.
Right now, for someone who has not yet done a brief here, even does not know. No platform does. Before anyone has completed a job, every signal available at signup is either something they said about themselves, which cannot be checked, or something trivial to fake, like uploading a few images. A skill rating typed in by the person being rated is not evidence, and putting a number on it would make it look like one.
So even does not show you a score it cannot stand behind. The shortlist is decided by whose turn it is, and the fields for style match and past quality sit at weight 0 and 0 in the code because there is no data behind them yet. When there is, they will start counting, and this answer will change.
What protects you in the meantime is not a rating. It is that you see finished work before you pay for any of it, and that if none of it is good enough you commission nobody and the project fee comes back to you.
